Hi Jony130, Thank you very much. I am a bit new to touchscreen boards. Is this the typical use for this power mosfet? I have alot on the board and they are all the same(see attached). I also noticed that the first 2 (u33, u32) from the left have the left side connections considerably different from #3-#7 (u35, u36, u37, u39, u40) on where as #3 -#7 have the left side connections all joined. Are these to power the infrareds? Thank you. Just trying to make sense of this.20190207_115000.jpg

Try reverse engineer the circuit or the part of it. And checks whatever the IRF7507 makes any sense.
